[U-Boot] : M29EW write buffer issue

[Jagannadha Sutradharudu Teki]

Hi,

The M29EW devices seem to report the CFI information wrong when it's in 8 bit mode.
Due to this the buffer size detected as 1024 bytes instead of 256.

I tried to fix this bug to initialize the 256 for these flash devices.
But when I tried to get the information from flash.

Bank # 1: CFI conformant flash (8 x 8)  Size: 64 MB in 512 Sectors
  AMD Standard command set, Manufacturer ID: 0xFF, Device ID: 0xFF
  Erase timeout: 4096 ms, write timeout: 2 ms
  Buffer write timeout: 5 ms, buffer size: 1024 bytes

Seems like the Manu.ID of this flash is 0x89, it got detected as 0xFF.

Is there any issues on cfi_flash.c respective of M29EW flashes, please let me know your inputs.

Thanks,
Jagan.
